Caps torque transducers

Torque tester for caps to measure the tightening torque, both during screwing and unscrewing, of bottle caps, drums, containers, jars, bottles, receptacles and jerry cans.

The cap torque transducers of the CAP-TT01 series are designed with the aim of measuring the screwing and removal torque of caps up to 11,5 Nm (100 lbFin).

Adjustable supports efficiently hold a wide range of container shapes and sizes, while optional flat and adjustable jaws are available for special profiles. The robust aluminum design and the simple and intuitive use allow the use in the laboratory and in production environments even by non-expert personnel.

The accuracy of ± 0,3% of the full scale and the incredibly fast sampling rate of 7.000 Hz guarantee precise and reliable test results, even in fast-acting applications.

The cap torque transducers of the CAP-TT01 family include a range of sophisticated production control support functions, including USB communication port, RS-232 port, Digimatic Mitutoyo interface, analog outputs, reset when the cap is removed, memory for 1.000 readings, indicators and good / reject outputs.

One is also available password protection to avoid unauthorized changes to settings and calibration.

CAP-TT01 cap torque transducers include MESUR Lite data acquisition software. MESUR Lite groups data in continuous or single point mode. The data stored in the CAP-TT01 memory can also be downloaded in a single block. The export of the detected data to Excel allows further analysis of the data and the generation of measurement reports.

Use of torque transducers for caps

CAP-TT01 series torque transducers for caps allow the easy and precise measurement of the torque required to start or unscrew the cap of bottles, flacons, jars, tubes and jerry cans.

The measurement takes place instantly and it is possible to memorize the peak value obtained. The peak value is particularly used to check the "breakout torque" of seals or the point of maximum stress of the cap.

The high sampling frequency allows to obtain a reliable peak measurement even if the event is short-lived.

Main characteristics

  • Optional mobile stands and jaws for a wide range of sample shapes and sizes.
  • Automatic exit, data storage and zeroing when removing the bottle cap helps automate testing processes
  • Password protection prevents unauthorized changes
  • The 7.000 Hz high-speed sampling rate accurately captures peak torque values
  • 5 selectable measurement units (ozFin, lbFin, lbFft, Ncm, Nm)
  • USB, RS-232, Mitutoyo and analog outputs
  • 1.000 data memory points with statistics
  • Programmable set point indicators and outputs for determining good / reject
  • Configurable audio alarms
  • MESUR Lite data collection software included

Details of the TT-01 series

torque transducers for caps

Easy and practical use

The torque transducers for caps are easy to use both on the work bench on the line and in the metrological laboratory. Furthermore, the support on the table is made in a stable way and above all not influenced by the force applied to the cap during the test operations. The sturdy structure allows the test to be carried out even on large bottles and containers or with particularly large diameter caps.


front display showing twist value

Highly readable front display

The instrument display, located on the front of the instrument, allows easy reading of the measured value and the functions that have been activated. The backlighting allows viewing even in poorly lit environments or directly on the line.


USB and digimatic connectors of the caps torque transducers

External connections

On the back of the instrument there is a connector for the connection of USB peripherals, peripherals with serial ports and Digimatic. It is also possible to generate an analog signal for connection to data acquisition systems.


acquisition software for cap torque transducers

Acquisition software

Included in the supply is the MEASUR Lite acquisition software which allows the display of measurements on a PC, the acquisition of torsion curves and the recording of data in Excel format.


Accessories for TT-01 series torque transducers
